Takahiro Hayashi. Energy trapping of circumferential resonant modes at a thin-walled groove in a hollow cylinder. Journal of the Acoustical Society of America, 2019, 146(4), EL376. https://doi.org/10.1121/1.5129561.
Abstract
Energy trapping of circumferential resonant modes at a thin-walled groove in a hollow cylinder is discussed using theoretical dispersion curves of guided waves, semi-analytical finite element (SAFE) calculations, and experiments. The analysis of the dispersion curves predicts the energy trapping at a thin-walled groove using the analogy of energy trapping of Lamb waves in a stepped plate. The energy trapping frequencies and displacement distributions at these frequencies were independently obtained with SAFE calculations and experiments. They agreed well with each other and proved that the energy trapping modes exist at the thin-walled groove in the hollow cylinder.
